I have no symptoms, but I would really like to get tested for herpes?

I'm somewhat of a hypochondriac and I recently found out that 90% or so of the people who have herpes never know and that freaks me out. Like I said, I've never seen any symptoms but it's going to drive me crazy if I don't know. So are there any clinics that provide blood testing? And if so how much does it cost? I don't want to go to my general care practitioner because I don't want my parents and my insurance co. to find out i'm taking a herpes test.
